Question

我试图将Android导航抽屉与页面（寻呼机）滑动标签条（https://github.com/Balaji-K13/Navigation-drawer-page-sliding-tab-strip）一起使用，但我无法使其正常工作。我正在使用android studio。我在主项目中进行了导入，并没有显示任何错误，但是当我遇到设备（虚拟或真实）时会出现此错误：

那么，想法？

我也试图实现它并得到了同样的错误。经过很多努力，我能够运行它但收到了你收到的类似错误。
我解决了这个问题 1：关闭并开始你的日食。 2：在所有库项目中复制主项目的v4 jar并删除现有项目。该错误是由于supportv4jar不匹配造成的。制作相同版本的所有supportv4jar 3：之后删除gen和bin文件夹并清理项目并运行。
